I had a power outage affect my server’s largeMDPagsalakayarray. Rather than let the server as a whole be down while waiting for it to complete anfsck, I had it boot without the large array so I could run the fsck manually.

Gayunman, when running it manually I realised I had no way of knowing how far it was and how long it would take to complete. This is especially problematic with such a large array. With a little searching I found the tip ofadding the -C parameter when calling fsck. I couldn’t find this in the documentation however: fsck –help showed no such option.

The option turns out to be ext4-specific, and thus shows a perfectly functional progress bar with a percentage indicator. To find the information, instead of “fsck –help” o “man fsck”, you have to input “fsck.ext4 –help” o “man fsck.ext4”. 🙂
